Backup and restore lab

Pick the restore chain for full/incremental/differential and GFS.

Build three restore chains: Thursday incremental, Wednesday differential, and the GFS monthly grandfather. RAID is not a backup.

GFS slots: weekly father and monthly grandfather sit besides this operational chain. RAID 1 on the file server is live redundancy, not a restore catalog.

1 · Incremental restore to Thursday

A spreadsheet was last known good Thursday 17:00. Policy for this restore is Sunday full plus daily incrementals. Select every tape required to rebuild Thursday. Do not use Wednesday’s differential for this chain — pick Wednesday Incremental instead.

Toggle every required tape. Order does not matter.
